Clinico-diagnostic studes on hepatic affections of aged buffaloes

الملخص EN

The study was conducted on 100 aged female buffaloes (average 7 years) slaughtered in the slaughter houses in Assiut Governorate, to clarify the parasitic and bacterial etiologic agents causing hepatic' affections as well as their histopathological picture.

Pre-slaughtering fecal samples by sedimentation technique revealed that 9 cases (9 %) were infected with Fasciola gigantica and 2 cases (2 %) with Fasciola hepatica.

Mixed infection with two species were detecting in 9 cases (9%).

Seventy six (76 %) of the investigated animals showed gross hepatic lesion, where 20 cases (26.32 %) were infected with adult Fasciola worm, 40 cases (52.63 %) showed chronic hepatitis (26.32 % multilobular cirrhosis ; 19.73 % biliary cirrhosis and 6.58 % Glissonian cirrhosis).

The last 16 cases (21.05 %) revealed necrotic hepatic lesions.

Bacteriological examination of these affected liver samples showed that 52 (68.4 %) revealed positive bacterial growth on culture media either in the mixed form (83.17 %) or in single form (16.83%).

AH fasciola infected livers showed positive bacterial isolation.

Multilobular cirrhosis was the most form of chronic hepatitis showing bacterial isolation (35.64 %) followed by biliary cirrhosis (13.86 %).

Staphylococcus spp.

represented the most prevalent bacterial isolation (43.56 %) followed by E.

coli (21.78 %) and Actinomyces pyogenes (15,84 %).

Streptococcus pyogenes and Enterobacter aerogenes were also recovered in proportion of 9.90 and 5.94 %, respectively.

It was concluded that livers of slaughtered aged female buffaloes showed a very high proportion of gross and histopathological lesions rather than they were considered as hazardous source of mixed different bacterial especially they showed positive Fasciola infection.
